GDS-15 is a brief geriatric-focused depression screening tool designed to reduce somatic symptom bias in older populations and support quick mood triage in outpatient, inpatient, and community settings.
Formula: GDS-15 total = sum of depressive-keyed responses (0-15).
Higher GDS-15 scores indicate greater late-life depressive symptom burden and support formal mood evaluation.
Use for depression screening in older adults across primary care, geriatric, and long-term care contexts.
GDS-15 depends on reliable self-report and may be less accurate in severe cognitive impairment or communication limitations without supportive assessment.
For related assessments, see PHQ-9, MDI Depression Scale and MoCA Score.
